ical details here set forth without in any wise affecting the spirit or nature of my invention.

`Having described my invention, what l claim is` 1. In a boat, a suitable propeller, shaft, means for imparting rotation to the drive-shaft, vintermediate gearing between 'said propeller and drive-shaft, a tilting frame mounted above the boat, a wind-wheel on said frame, a suitable shafting 'carried by the frame for transmitting power from the windwheel, and means for cooperatively connecting said shafting with the drive-shaft upon the tilting of the frame in one direction, substantially as set forth.

2. In a boat, a suitable propeller-shaft, a drive-shaft, cran -armson saidv drive-shaft, actuating-levers pivoted lto the boat, connectlatch 23 is swung to an unlocked position and ythe shaft is shifted to move the pinion 21 out of alinement with the gear 6, when again the shaft 20 is locked by a similar latch 23 on the opposite standard l bearing against the adjacent end of the shaft and hooking over a similar pin 24. When, however, the frame F is in a vertical position and the bevel-pins 18 19 are in mesh, the shaft 17 is adapted to assist in the rotation of the gear-wheel 6 through the connections described, the said shaft 17 being set into operation by awindwheel A, whose shaft is mounted in the upper terminal fork 25 of a sleeve 26, through which the shaft 17 passes, the wind-wheel shaft'carrying a bevel-gear 27, which meshes with a bevel-pinion 28 at the upper end of the shaft 17. When the wind is favorable, therea drivefore, the frame F may be swung into a verticoupled to the wrist-pins of said crank-arms, cal position to efect connection between the intermedia gearing between the propeller? wind-wheel and the drive-shaft 2 in the man- .shaft and ive-shaft, atilting frame mounted ner indicated, the wind-vheel under the circumstances either supplementing the work of the occupants of the boat or relieving them altogether, as the case may be. When the] wind is to be relied on altogether, the conupon the swinging of said frame in one dir ccs neeting-rods 4 4 may be disconnected from j tion, substantially as Set forth. the crank-arms and allowed to rest on the bot` i 3. In laboansuitable standards,a drive-shaft. tom ofthe boat. l mounted. on thel same, a propeller-shaft, inl The purpose ofb the sleeve 26 is to enable l termediate gearing between the propellerl; 1* cal position and to adjust the angular position of the Wind-wheel in relation to the direction of the wind, this locking and adjustment being accomplished as follows: Phe base of thc 1n proximity to the drive-shaft, a wind-Wheel carried b/y said frame, and suitable shafting cooperatively connected to the wind-wheel drive-shaft, a tilting frame mounted to swing f vertically on the standards, a shaft disposed i longitudinally in said frame, and radapted to have'onecnd coperatively connected to the sleeve (which, by the waI is freely rotatable i aforesaid gearwheel, a rotatable sleeve enin 'its bearings) is provided with a disk 29, veloping` the shaft on the frame,an upper teralong whose upper face are disposed'a series l minal fork carried by said sleeve, a windof radial arms 30, projecting beyond the' pe- I wheel shaft on the fork, a bevel-pinion on the riphery of the disk, the free ends of which shaft, a corresponding pinion on the upper are adapted to engage an opening 31 at the l end of the longitudinal shaft meshing' with cnil of a spring arm or latch 32, whose fixed t the afolyesaid pinion, means for rotating th(- und is secured on the inner face of one of the course, that I may depart fromA the mechan-y and adapted to be coupled to the drive-shaftl operator to lock the frame F in its vertishaft and drive-shaft, a gearwheel on the' sleeve ifo effect the proper angular adjust`V ing-rods carried by the levers and detachably below' ing'the sleeve when oncel adjusted, substantially as set forth. i

4. ln'aboaa va suitable oscillating frame, a rotatable sleeve disposed'longtudinallythereof, a shaft in said sleeve, a bevel-pinion at the lower end of theshaft, a longitudinallyslidingushaft mounted in suitable standards e frame,- a bevel-pinion on said sliding shaft," andI locking-latches pivoted to the standards and adapted tobear against the ad jacent ends of the slidngshaft upon proper adjustment of the latter; and look the same in position, Asubstantially as set forth.

5.` In a boat, suitable standards, propelling mechanism mounted on the'samegga-tilting frame pivotally carried at the upper nd 'of the standards, a Wind-wheel at the free upper end of the frame, a shaft disposed longitudinally withA the frame and cooperatively connected to the wind-wheel, and adapted to be coupled to the main propelling mechanism upon tilting the frame to a vertical position, a sleeve enveloping the shaft on the.

frame, a series of radially-disposed arms fixed to the sleeve, and a spring-latch engaging any one of thearms for locking thesleeve, substantially as set forth.

6. In a boat. a suitable propeller-shaft, a

merit for the wind-wheel, and means for lock# BEST AVAILABLE COPY frame mounted above the drive-shaft, a winde wheel on said frame, a suitable shafting car V`ried by the frame fortransrnitting power from the wind-wheel, and means for cper atively connecting said sha'ting With the main drive-shaft upon thetilting of said frame to an uprightposition;substantially as set forth. 7 In a boat, a longitudinally-disposed propeller shaft, standards carried by the boat,

propelling mechanism mounted between the.

standardsl -a longitudinally tilting I,frame mounted on top of the standards, brackets for supporting said frame in its lowest position, a `wind-Wheel at the free upper end of the frame.. and suitable gearing actuated by the rotation of said wind-wheel and adapted to be brought into cooperative connection with he main propellingy mechanism of the boat upon the tilting of said frame from its position on said brackets,substantially as set forth. 1n testimony whereof Iailix mysignaturein presence of two witnesses.
